Mortar truck

Abstract

The invention provides a mortar trolley. The mortar trolley comprises a trolley body, a transmission device, a stirring system and a slurry discharge device. The stirring device comprises a stirring tank and a stirring shaft. The stirring shaft is arranged in the stirring tank, the stirring tank is arranged on the trolley body, and a slurry outlet of the stirring tank is formed in the bottom of the stirring tank end; the slurry discharge device comprises a first driving motor and a slurry outlet pump; the transmission device comprises a second driving motor, a driving wheel, a driving belt and a driven wheel; the driving wheel is driven by an output shaft of the second driving motor to rotate, the driving wheel and the driven wheel are transmitted through the driving belt, the driven wheel is connected to the stirring shaft, and the slurry inlet of the slurry discharge pump is connected to the slurry outlet of the stirring tank. According to the mortar trolley provided by the invention, mortar left in the stirring tank is conveniently cleaned; the transmission deice and the slurry discharge pump are prevented from being damaged by solidified mortar in the stirring tank, so that mortar is normally transported; the mortar conveying speed is increased; on the premise of satisfying the operating requirements of the trolley body, the space required for mounting a wheel set assembly is reduced, and the production cost of the mortar trolley is lowered.

Description

technical field [0001] The invention relates to the technical field of mortar equipment, in particular to a mortar truck. Background technique [0002] At present, in the domestic subway shield construction, industrial and mining locomotives, mortar trucks, muck trucks, segment trucks, etc. constitute the auxiliary part of shield tunneling, which is a necessary condition for the normal operation of the shield machine. Mortar truck is an important type of supporting vehicle for industrial and mining locomotives. The mortar transportation task in subway shield construction has the advantages of large capacity, low center of gravity, convenient and reliable drag scheme, convenient maintenance, and coherent construction organization system. With its superior performance and reasonable way of producing mortar, it is widely used in many tunnel shield constructions. The existing mortar trucks on the market are divided into 4m by volume 3 ~13m 3 , to meet the tunnel shield constr...

AI Technical Summary

Problems solved by technology

[0004] However, the existing mortar vehicles mainly have the following problems: 1) the existing slurry discharge device is arranged under the middle of the vehicle body, which is not convenient for construction personnel to clean the mortar deposited in the vehicle body and pipelines

And the mortar that has not been cleaned for a long time will solidify in the car body, the slurry pump and the mortar pipeline. The driving wheel, worm gear reducer or slurry pump is damaged

2) In the existing running part of the car body, the axle box composed of the bearing and the front and rear covers of the wheel is mainly arranged outside the wheel, which takes a long time to manufacture and process, consumes time and materials, and requires a large space for installation
